FIG. 4 is an exploded view showing a conventional electrical junction box. - An electrical junction box according to an embodiment of the present invention will be explained with respect to
FIGS. 1 to 3 . The electrical junction box of the present invention is mounted on a vehicle and supplies electric power and signals to on-vehicle electronic devices. Further, in the present invention, a junction block (or a junction box), a fuse block (or a fuse box), and a relay block (or a relay box) are hereinafter collectively referred to as an electrical junction box. - The electrical junction box includes: a synthetic-resin-made cassette block 1 shown in
FIG. 1 ; and a synthetic-resin-made case main body (not shown) for receiving the cassette block 1. Further, the cassette block 1 and the case main body define a frame in claims. - Electronic components such as relay or fuse are mounted on an
upper surface 1 a of the cassette block 1, and a bus bar and a terminal are inserted into alower surface 1 b of the cassette block 1. The bus bar is a wiring member made by pressing a metal plate or the like. The terminal is attached to an end of an electric wire. Thelower surface 1 b of the cassette block 1 is provided with a bus bar receiving portion 2 (corresponding to the component receiving portion in claims) into which the bus bar is inserted, a terminal receiving portion 3 (corresponding to the component receiving portion in claims) into which the terminal is inserted, ahollow cavity portion 4 adjacent to the busbar receiving portion 2 and theterminal receiving portion 3 and into which no component is inserted, and aninsertion portion 6 into which the bus bar and an input power line connected to the bus bar are inserted. Further, alocking portion 10 for locking with the case main body is provided on a side surface of the cassette block 1. - The bus
bar receiving portion 2 is formed in a groove shape able to receive the bus bar. The terminal receivingportion 3 is formed in a rectangular tube shape able to receive the terminal. Lower ends of the busbar receiving portion 2 and theterminal receiving portion 3 are aligned at the same height. Theinsertion portion 6 is formed in a rectangular tube shape, and adjacent to the busbar receiving portion 2. A lower end of theinsertion portion 6 is projected about 10 mm from the lower end of theterminal receiving portion 3. - The
hollow cavity portion 4 is formed in a tube shape by an outer surface of a wall defining the busbar receiving portion 2, an outer surface of a wall defining theterminal receiving portion 3, an outer wall of the cassette block 1, and apartition wall 5 partitioning thehollow cavity portions 4 adjacent to each other. Thepartition wall 5 is provided for increasing the rigidity of the cassette block 1. Further, a mesh portion B and a diagonal portion C inFIG. 3 are thehollow cavity portions 4. - Further, among a plurality of
hollow cavity portions 4, a lower end of thehollow cavity portion 4 positioned in the mesh portion B inFIG. 3 is positioned 1 to 2 mm nearer theupper surface 1 a than lower ends of the busbar receiving portion 2 and the terminal receivingportion 3. Further, among a plurality ofhollow cavity portions 4, a lower end of thehollow cavity portion 4 positioned in the diagonal portion C inFIG. 3 is aligned at the same height with the lower ends of the busbar receiving portion 2 and the terminal receivingportion 3. The lower end of thehollow cavity portion 4 positioned in the mesh portion B is alower end 5 a of thepartition wall 5 positioned in the mesh portion B. As shown inFIG. 2 , thelower end 5 a of thepartition wall 5 is positioned a size h nearer theupper surface 1 a than alower end 3 a of the adjacentterminal receiving portion 3. The size h of this embodiment is, as described above, 1 to 2 mm. - This size h allows the bus
bar receiving portion 2 and the terminal receivingportion 3 to be easily distinguished from thehollow cavity portion 4 and allows the rigidity of the cassette block 1 not to be reduced. In the present invention, the size h is within 1 to 5 mm. Further, the most preferable size h in the present invention is, as described above, within 1 to 2 mm. - According to such an electrical junction box, because the
lower end 5 a of thehollow cavity portion 4 positioned in the mesh portion B inFIG. 3 is positioned 1 to 2 mm nearer theupper surface 1 a than the lower ends of the busbar receiving portion 2 and the terminal receivingportion 3, thehollow cavity portion 4 is easily distinguished from the busbar receiving portion 2 and the terminal receivingportion 3, and the workability upon respectively inserting the bus bar and the terminal into the busbar receiving portion 2 and the terminal receivingportion 3 is improved. Further, if thelower end 5 a of thehollow cavity portion 4 is projected further than the lower ends of the busbar receiving portion 2 and theterminal receiving portion 3, it is difficult to respectively insert the bus bar and the terminal into the busbar receiving portion 2 and theterminal receiving portion 3. However, in this electrical junction box, because thelower end 5 a of thehollow cavity portion 4 positioned in the mesh portion B inFIG. 3 is positioned nearer theupper surface 1 a than the lower ends of the busbar receiving portion 2 and theterminal receiving portion 3, the workability upon inserting the bus bar and the terminal is not reduced. - Further, in the above electrical junction box, the reason why only the
lower end 5 a of thehollow cavity portion 4 positioned in the mesh portion B inFIG. 3 is positioned nearer theupper surface 1 a than the lower ends of the busbar receiving portion 2 and the terminal receivingportion 3, and the lower end of thehollow cavity portion 4 positioned in the diagonal portion C is aligned at the same height with the lower ends of the busbar receiving portion 2 and the terminal receivingportion 3 is as follows. - Namely, a size of the opening portion of the
hollow cavity portion 4 positioned in the mesh portion B inFIG. 3 is similar to a size of an insertion opening of the adjacentterminal receiving portion 3. Therefore, there is a fear that the terminal may be inserted into thehollow cavity portion 4. For preventing this, thelower end 5 a of thehollow cavity portion 4 is positioned nearer theupper surface 1 a than the lower ends of the busbar receiving portion 2 and theterminal receiving portion 3. - In contrast, a size of the opening of the
hollow cavity portion 4 positioned in the diagonal portion C inFIG. 3 is slightly smaller than a size of the insertion opening of the adjacentterminal receiving portion 3 and prevents the terminal from being inserted into the opening even if mistakenly tried to insert the terminal into thehollow cavity portion 4. Therefore, the lower end of thehollow cavity portion 4 is aligned at the same height with the lower ends of the busbar receiving portion 2 and theterminal receiving portion 3. Further, in thehollow cavity portion 4 positioned in the diagonal portion C inFIG. 3 , there is no fear that the terminal may be mistakenly inserted. However, for easily distinguishing thehollow cavity portion 4 from theterminal receiving portion 3, of course there is no problem that the lower end of thehollow cavity portion 4 may be positioned nearer theupper surface 1 a than the lower ends of the busbar receiving portion 2 and theterminal receiving portion 3. - Further, according to the above embodiment, the cassette block 1 is separated from the case main body. However, according to the present invention, the cassette block 1 may be integral with the case main body.
